Ben Edmondson, John Malcolm-Hansen, Naved Arif (not sure 'cause I think he's banned from cricket).
Pretty much. Not sure how much JMH would actually strengthen the side, though, and Naved Arif might, but he's a bell-end. I included him solely because his ban came from the ECB, so he'd probably be okay to play for Denmark as long as he didn't represent them in the knockouts.
The only one who really has to come in is Ben Edmondson for Basit Raja.
EDIT -
Actually, looking at your squad, you might want JMH and Carsten Pedersen in for Zameer Khan and Zishan Shah
